LAMP.

SPECIFICATION forming part of Letters Patent No. 471,282, dated March22, 1892.

Application filed August 12, 1891. Serial No. 402.430. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. VAN HISE, a citizen of the United States,residing in the city and State of New York, have invented an Improvementin Lamps, of which the follow-' ing is a specification.

This invention is a modification of and improvement upon the device setforth in my patent, No. 458,509, granted August 25, 1891, and thepresent invention is for adapting the improvement to an Argand lamphaving a wick that is cylindrical throughout its length; and theinvention consists in the combinations of devices hereinafter set forthand claimed.

In the drawings, Figure 1 is a vertical section of the lamp complete.Fig. 2 is a sectional plan at about the line as :0. Fig. 3 is asectional plan at the line y y; and Fig. 4 is a detached view of aportion of one of the reservoirs, showing the thumb-disk and catch ofthe regulator-rod. In Figs. 2, 3, and 4 the parts are shown in largersize than in Fig. 1.

This lamp is especially intended for streets, parks, gardens, &c., Wherethe lamp is required to burnacertain number of hours, and by the presentinvention the lamp is automatically extinguished at or about the desiredtime, in consequence of the consumption of the oil acting through afloat, by the extinguishing devices.

I have represented in the drawings three reservoirs A B 0, connectedtogether by the tubes D D, and at 2 upon the reservoir A is a suitablescrew-cap to allow for filling the reservoirs, and there may be a cockat the lower end of the reservoir A, by which the contents of thereservoirs can be drawn off. Through the reservoir B is an air-tube E,and the wick F surrounds this air-tube, and there is a Wick-tube Goutside of the wick. These parts are constructed in any usual or desiredmanner. I have represented the Wick-tube G as provided with adownwardly-projecting rim 5, setting within the upper end of thereceiver B, and I have represented a wick-' raiser H and rod H foradjusting the wick.

The cylinder K surrounds the receiver B, there being an air-spacebetween them, and there is a deflector L at the upper end of thecylinder K and an air-distributer K for directing the ascending currentof air to the flame. W'ithin the air-tube E is a central rod N, fittedto slide freely in suitable bridges or supports 7, and at the upper endof this rod is a deflector or button 0, which acts as a flame-spreader,and its under edge is preferably lnade as an annular groove 8, the sizeof the deflector and the groove being such that when the deflector isdropped it will act as an extinguisher by entirely covering the upperend of the Argand wick, and I prefer to connect with thedeflector-button a perforated cylinder P to act as an air-distributerWithin the flame.

I make use of the spring-latch 9 at the button end of the rod N in sucha position that when this spring-latch is in action to hold up the rod Nand deflector 0 it will be at the proper height for the flame to burnproperly, and when this latch is moved aside the rod N and deflector Oare unsupported and drop and the flame is instantly extinguished. Inorder to raise the rod and deflector into the proper position forlighting the lamp, the rod itself may be pressed up with the finger; butI have represented a lifter 10, connected to the rod and extending downbelow the bottom of the lamp as a convenient device against which thefinger can be pressed in restoring the parts to the normal position.

Within the vessel 0 is a float Q, connected to the lower end of aregulator-rod R, which passes up into one of the tubes S, that supportthe cap S of the lamp, and this regtr lator-rod has projecting from itranges of pins, as indicated at a. There is a thumb-disk 13 within thechamber 14 at the bottom of the tube S, and the metal of this chamber isremoved at one or opposite sides to give access for turning thisthumb-disk 13 and the regulator-rod B. to bring either range of pinsinto position to act upon the drop-lever T, which is pivoted at 16 andhas a rod 17 extending to and acting upon the spring-latch 9. I haverepresented this rod 17 as within a tube passing through the receiver B;but the connection may be made in any convenient manner.

It is to be understood'that any desired numfor determining the period oftime during which the lamp is allowed to burn, and when one pin ineither range comes into contact with the end of the lever T that end ofthe lever is carried down as the oil is consumed and the other end ofthe lever T and the rod 17 are raised, and when the pin passes clear ofsuch lever, so as to liberate the same, the rod 17 drops and the end ofthe rod 17 strikes the end of and moves the spring-latch 9 and releasesthe central rod N, so that this red and the deflector drop andextinguish the light, and this downward movement of the rod 17 ispromoted by a spring T, that is fastened to the inner wall of thereservoir 0 and acts upon the inner end of the lever T to raise the sameas the pin on the rod passes clear of such lever, and when the lamp isagain to be lighted the deflector and red are raised, the

spring-lateh passes beneath the rod and holds the same. The lever T isbeneath the n ext pin in the range of pins ready to be depressed andagain liberated when the oil has been consumed sufficient-ly to allowthe float to descend and liberate the drop-lever from the pin. Thisdrop-lever may be constructed in any desired mannersuch, for intance, asthat represented in my aforesaid patent. I have, however, representedthe same with a catch 2st at the end, which yields as the rod R islifted, so that the catch may pass by one of the pins and catch beneaththe same, and the rod 17 is thereby held up until the pin passes clearof the end of the drop-lever as the float descends.

The rod 17 does not act upon the springlatch while being drawn up, andin falling the red by its inertia strikes the end of the spring latch 9and throws the latch far enough away to allow the rod N to drop. I haverepresented this latch as having a mor tise that is large enough for therod to drop through, as seen in Fig. 2, and when the rod N is raised thespring-latch returns to the position shown in Fig. 1, with the end ofthe latch against the side of the rod 17, and when this red 17 is liftedthe latch will spring suffieiently for the end of the latch to come intothe path of the rod 17 so as to be acted upon thereby when said rod isdropped.

It is to be understood that the regulatorrod R slides through thethumb-disk 13, and

that upon the edge of this thumb-disk there may be marlgs or numbers toindicate the number of hours that the lamp will burn when the disk hasbeen turned to expose such number at the opening in the chamber 14-, andit is preferable to notch the disk 13, asshown in Fig. 3, and to providea spring 25 to set into a notch and prevent the disk being accidentallyturned.

I claim as my invention 1. The combination, with an Argand lamp, the rodN, passing through the air-tube, and the deflector upon its upper end,of a float within the receiver, a regulator-rod connected therewith andhaving projections, a droplever acted upon by the projections, and aspring-latch for holding up the central rod and deflector, and whichlatch is moved by the drop-lever and rod to allow the deflector to falland extinguish the flame, substantially as set forth.

2. The combination, with an Argand lamp, of the central rod passingthrough the airtube and having a deflector or button upon its upper end,the spring-latch forholding up the rod and deflector, a lifter connectedwith the central rod, a float within the receiver of the lamp, aregulator-rod having ranges of pins projecting therefrom, the pins inthe different ranges being at different distances apart, a thumb-disksurrounding the regulator-rod and adapted to be turned by hand forturning the regulator-rod, a drop-lever having a latch at the end, and arod extending from the drop lever and acting upon the spring-latch fordropping the deflector and extinguishing the flame when one of the pinson the regulator-rod separates from the droplever, substantially as setforth.

The combination, with an extinguisher, of a rod connected to the sameand passing to the bottom of the lamp, a spring for holding the rod, afloat in the reservoir, :1. series of pins connected with the float, anda lever and connection to move the spring and allow the extinguisher toact, substantially as specified.

Signed by me this 11th day of August, 1891.
